Recent python versions complain when backslashes in strings create invalid escape sequences. This causes issues for strings used as regex patterns like `'^List\[(.*)\]$'` where you want the regex parser to treat `[` and `]` as literals. Double-backslashing is one way to fix it but simply converting the string to a raw string `re.match(r'^List\[(.*)\]$', text)` is easier and less error prone.
This directory contains templates and template processing code for generating HTTP bindings for the RESTful API's. The RESTful API's are declared using [Swagger][swagger]. While Swagger provides a [code generating toolkit][swagger-codegen], it requires Java to run, which would be an unusual dependency to require for Asterisk developers. This code generator is similar, but written in Python. Templates are processed by using [pystache][pystache], which is a fairly simply Python implementation of [mustache][mustache].
